Running Test FX Tests (JDK 7 Doesn't Work... JDK 8 Does)

[Lane Feltis]

Note: Henrik, thanks for releasing 3.1.2 and fixing the window size issue, it is working perfectly now!

I have been using JDK 8 because it is the only version that I can successfully run Test FX tests with. If I run it using JDK 7 (latest release 51, early adopter 60, previous version 45, 25 or 6) I get the following error...

...however, if I have any version of JDK 8 installed, it works fine. My issue is that I am trying to get code coverage into our build and ideally I would like to use the out of the box jacoco plugin for gradle. For some reason, jacoco (and other code coverage plugins I tried) don't play so nice with Test FX and Java 8. Since Test FX was designed for Java 7, I was hoping to rollback to a Java 7 version to more easily get code coverage integrated. Is anyone else having trouble even running simply tests in Java 7? I am trying to run this simple test below and I am getting the error above...

import javafx.event.ActionEvent;

import javafx.event.EventHandler;

import javafx.scene.Parent;

import javafx.scene.control.Button;

import org.junit.Test;

import org.junit.experimental.categories.Category;

import org.loadui.testfx.GuiTest;

import org.loadui.testfx.categories.TestFX;

import static org.loadui.testfx.Assertions.verifyThat;

import static org.loadui.testfx.controls.Commons.hasText;

@Category(TestFX.class)

public class SimpleButtonTest extends GuiTest {

    @Override

    protected Parent getRootNode() {

        final Button btn = new Button();

        btn.setId("btn");

        btn.setText("Hello World");

        btn.setOnAction(new EventHandler<ActionEvent>() {

            @Override

            public void handle(ActionEvent actionEvent) {

                btn.setText( "was clicked" );

            }

        });

        return btn;

    }

    @Test

    public void shouldClickButton(){

        final Button button = find( "#btn" );

        click(button);

        verifyThat( "#btn", hasText("was clicked") );

    }

}

...any thoughts? Can you run this simple test in Java 7? Thanks!

Does it work without jacoco?

I run the test that you posted from IntelliJ on Windows and it was successful:

I was running it without Jacoco or anything else, just to try to get this simple Test FX file working. I am developing on a MAC... I'll see if I can get it working on Windows and provide some more feedback, thanks.

[Lane Feltis]

I verified that this works on Windows 7, but I am still unsure why it is failing on a MAC. If anyone has this working on a MAC, please provide details of your environment and setup. Thanks!
